Bounding Box

First of all i must say that Demina is a great lib; it does everything its is supposed to do and even interpolation between animations! Great!

Im a beginner with Demina, and i want to know if there is a way to get the bouding box of an entire animation in a specific key frame, or maybe in the current key frame since i want to automate physics objects creation.

Unfortunately no, there's nothing like that built into Demina. I think this would be pretty hard to do accurately at runtime, since you'd have to analyze the images and disregard the transparent areas to make a bounding box. A few people (myself included)
have talked about building an external tool where you could design hitboxes and collision volumes, but nobody has done any work in that direct yet.

Unfortunately, since it gets the width and height from the input texture, the rectangles don't necessarily match the shape of each bone. You can see that in the screenshot. Every box is two times the size of its contents. However, it wouldn't be too hard
to run over the pixel data in the editor to generate bounding boxes.

In general, I think traditional hitboxes would be more useful, but if this is something people find helpful, I can try to add it.
